PMP certification--is it worth pursuing?

I am a certified PMP, passed the exam in Oct2006. There was a lot of hype about PMP at that time. I thought it will be a good to add onto my resume. I did a course conducted by the PMI Ottawa valley chapter. It was an exam preparation course, that ran for 9 weeks. After attending the course, I had to prepare for atleast 6 weeks religiously. I had to read through the book thoroughly atleast twice. I hadn't done this kind of preparation even for my Engineering final exams. The exam was also quite tough, with all four hours barely enough to complete the test. I was just happy to see the pass grade at the end of the exam.

After getting PMP certified, i felt good that I had achieved something. However, the next process was to maintain the PDUs. I found that it is a time consuming and expensive affair. All courses/seminars offered by PMI institute were atleast 80$ for 3 to 4 PDUs and I needed ~60 PDUs to maintain PMP certification.

I realised that I could give seminars and collect PDUs. I did one seminar in a university in India. I am hoping that will count for a few PDUs. I do have a fair bit to collect before end of next year. I did see that pmstudy.com is offering cheaper ways to collect PDUs. Their online courses are a lot cheaper than courses conducted by PMI.

All in all, I think the PMP certificate is good to have on the resume to help find a job. In the tech sector, it doesnt matter if one is a certified PMP or not. Government project management jobs do require PMP certification.
